Today's Piano Puzzler

I figured that amid all the party frivolities tonight we'd end the year with a Piano Puzzler, and this week's contestant is Matthew Rhea from Fishers, Indiana.  And the song should be easily guessed.  The hidden composer likely will fall between a couple of possibilities.  And happily I got it.  (For basically the same reasons that the contestant says that made him of the correct composer, as well.)  A good way to head into the year.
